Rdkit add atom to molecule

WebSep 1, 2024 · The RDKit implementation picks the atom with the smallest Morgan invariant. This way the choice is independent of the atom order in the molecule. In the case of symmetric atoms a and/or d, the RDKit implementation stores all possible torsional angles in the TF instead of only storing the smallest one as in the original approach.
